Too much of a good thing can be definitely bad for us. But a new study published Friday in JAMA Network Open suggests that exercise is a clear exception. It found that any level of cardiovascular fitness—including the kind you’d see from elite athletes—is linked to staying alive longer.

A daily low dose of aspirin won’t help healthy older people stay alive any longer, suggests new research published this week in the New England Journal of Medicine. It might even raise their risk of dying early of certain things, like cancer.

New research published in the journal JAMA Internal Medicine shows that eating added sugar in foods such as soft drinks, cereals, and cakes does more than just make us pack on the pounds, it can also increase our risk of dying from heart disease — and by a significant margin.

Cholesterol is bad and lowering cholesterol is good. Well, at least this is what we’ve been led to believe for nearly four decades. But it’s a misconception — a big, fat stinking lie. Here’s what we’re learning about cholesterol — and what it really means to your health.

Everyone — everyone — knows that smoking is terrible for you. But damn, according to a massive new study published in Circulation (a journal of the American Heart Association), even one cigarette a day could be very harmful to your health.
